Description

Power electrical contact device, replaceable power electrical contact module and power electrical connector

Technical Field

The present invention relates to a power electrical contact device, in particular a high current contact device, or an electrical power contact device, for a power electrical connector. The invention also relates to a replaceable power electrical contact module, in particular to a replaceable high current contact module or a replaceable electrical power contact module for a power electrical connector. The invention also relates to a power electrical connector or power electrical mating connector, in particular a high current connector or electrical power connector, for example for the field of three-phase currents or for the field of electric vehicles.

Background

In the electrical field (electrical engineering, electronics, electrical power engineering, etc.), a large number of electrical connector devices or connector arrangements, socket and/or pin connectors, etc., hereinafter referred to as ((power) electrical) (mating) connectors, for the purpose of transmission of electrical currents, voltages and/or signals over a large range of electrical currents, voltages and/or frequencies are known. In the low-voltage, medium-voltage or high-voltage range and/or in the medium-current or high-current range, and in particular in the field of three-phase currents, connectors of this type must ensure that the current, voltage and/or signal is transmitted permanently, repeatedly and/or after a relatively long service life (possibly after a short time) in a warm, possibly hot, polluted, moist and/or chemically corrosive environment.

Due to the wide spread of applications, a large number of connectors with special designs are known. A connector of this type or a housing of a connector of this type may be mounted to a cable, line or the like, and/or an electrical device or device, e.g. on/in a housing of an (power) electrical component or device of this type; in the latter case, the connector is generally referred to as a (mating) connector device. If the connector is located only on a cable or the like, said connector is usually called a (flying lead) (plug) connector or plug (usually with pin contact means) or a coupling (usually with plug contact means); if the connector is located in/on a (power) electrical component, it is often referred to as an (embedded) connector, such as an (embedded) plug or an (embedded) socket.

Power electrical connectors must ensure problem-free transmission of electrical power, wherein the connectors (connector and mating connector) corresponding to each other usually have fastening or locking means for permanently, but usually releasably fastening or locking the connector onto/into the mating connector. Furthermore, corresponding power electrical contacts, such as socket contacts, pin contacts, tab contacts, etc., must be securely housed in the connector. Efforts are continually being made to improve and/or make more cost effective power electrical connectors.

For example, a charging connector for electric cars requires a power electrical contact device, which must transmit a current of about 32A (power contact device, ground contact device) at a peak voltage of about 500V and at an outside temperature of about-30 ℃ to about +/-50 ℃. The signal contact means has a current of about 2A at a voltage of about 30V. The service life of this type of charging connector should be approximately 10 to 15 years, wherein, depending on the environment (moisture, dust, salt, etc.), it should be possible to perform 10000 to 20000 plug connection cycles with this type of charging connector, wherein this is preferred when a permanently low contact resistance is also achieved. In order to achieve this number of plug connection cycles with a relatively low contact resistance, the contact means must be coated, which again increases the cost of the contact means.

Disclosure of Invention

The object of the present invention is to provide an improved power electrical connector or an improved power electrical mating connector, in particular a high current connector or an electrical power connector, for example for use in the field of three-phase currents or in the field of electric vehicles. In this case, the connector should be designed to achieve 10000 to 20000 plug connection cycles depending on the environment in which the connector is used, wherein the contact means of the connector should be relatively cost-effective. In particular, in this case, it should be possible to dispense with a relatively expensive coating of the contact device.

The object of the invention is achieved by a power electrical contact device for a power electrical connector, in particular a high current contact device or an electrical power contact device, according to the independent claims; this is achieved by a replaceable power electrical contact module for a power electrical connector, in particular a replaceable high current contact module or a replaceable electrical power contact device; and by a power electrical connector or power electrical mating connector, in particular a high current connector or an electrical power connector; preferably in the field of three-phase currents or in the field of electric vehicles. Advantageous developments, additional features and/or advantages of the invention are set forth in the dependent claims and in the following description.

The power electrical contact arrangement according to the invention comprises a power electrical contact section and a power electrical connection section, wherein the contact section is configured as a first power electrical contact means and the connection section is configured as a second power electrical contact means. Power electricity means that the contact means are suitable for voltages above e.g. 24V, in particular above 48V, e.g. about 500V; for currents above 4A, in particular currents above 12A, for example currents of about 32A; and/or a signal above 500mA, in particular a signal above 1A, for example a signal of about 2A. It goes without saying that higher values can be used.

In this case, the contact arrangement or the first contact means can be configured for a replaceable power electrical contact module. The two contact means for a single contact arrangement may be arranged separate from each other. Two contact means which can be separated from one another or can be mounted to one another can also comprise in each case a power electrical contact section region in which they can be electrically disconnected from one another or can be electrically connected to one another. In this case, the two contact means may also comprise a mechanical contact region in which they are mechanically decoupled from one another or mechanically connectable to one another.

According to the invention, the contact device is configured in at least two parts. In this case the contact means can be held together as a single piece as the contact device. I.e. the (at least) two parts of the single contact arrangement, i.e. the first contact means and the second contact means, are configured to be separated from each other, i.e. to be separated from each other, either electrically and/or mechanically, respectively, before being mounted to each other. In an embodiment, the first contact means and the second contact means may be electromechanically coupled to each other by a single releasable connection. The electromechanical connection may be configured as an active and/or an inactive connection, wherein the connection is preferably configured as a plug connection, a threaded connection, a latch connection or a snap action connection.

In this case, the electromechanical connection is preferably configured to have (at least) partially a complementary shape and/or a complementary function. In addition, a weak bond connection (contact adhesive, detachable adhesive) can be provided in this connection. The connection of the contact means may be configured such that the first contact means may be easily separated from the second contact means by hand or a tool, or vice versa. This is preferably done without damaging either of the two contact devices. In particular, this is achieved in such a way that, when one contact means is replaced, the respective other contact means which are not ready to be replaced are not damaged.

In an embodiment, the first contact means has a contact region by means of which an electrical and/or mechanical contact can be established with the power electrical mating contact device. In an embodiment, the second contact means have a connection area to which the cable can be electrically connected. In an embodiment, the first contact means may have a contact means mounting section onto/into which the second contact means may be mounted or mounted. Furthermore, the second contact means may have a contact means mounting section onto/into which the first contact means may be mounted or mounted. In this case, the contact device mounting section may be configured to have, in part, a complementary shape and/or a complementary function.

In an embodiment, the first contact means may have a housing mounting section, by means of which the first contact means may be directly or indirectly mounted or mounted onto/into the contact section socket. Furthermore, the second contact means may have a housing mounting section, by means of which the second contact means can be mounted or mounted directly or indirectly on/in the connector housing. In this case, the housing mounting section cannot be configured to have a complementary shape or a complementary function. In the case of a mounted contact arrangement, the contact means mounting section of the mounted contact arrangement constitutes an electromechanical connection or an electrical and mechanical contact area.

In this case, the contact means mounting section preferably partially guides one into the other. Furthermore, the contact means mounting sections in this case preferably overlap in the axial direction and/or the direction of travel of the contact arrangement. Furthermore, the contact means mounting section may be manually centered. That is, the contact means mounting section of one contact means is centered, e.g. radially on the outside of the contact means mounting section of the other contact means, while the contact means mounting section of the other contact means is radially centered on the inside of the contact means (possibly on the inside of the contact means mounting section or even on the inside of the housing mounting section).

Furthermore, the housing mounting sections of the mounted contact devices can be spaced apart from one another in the axial direction, wherein the housing mounting sections can have substantially the same or different (outer) diameters or the same or different (outer) dimensions. The housing mounting section of the individual contact means may be arranged radially beyond or outside the contact means mounting section of the individual contact means. Furthermore, the housing mounting section and the contact means mounting section of the same contact means may preferably overlap each other in the axial direction; i.e. the contact means mounting section may protrude slightly into the interior of the housing mounting section. It goes without saying that the housing mounting sections can be arranged at a distance from the contact means mounting sections of the same contact means, preferably in the axial direction.

The contact device mounting section of the first contact device may comprise a contact spring ring or a contact pin. The contact device mounting section of the second contact device may similarly comprise a contact pin or a contact spring ring. Furthermore, the contact means mounting section of the first contact means may comprise an internal thread (threaded recess) or an external thread (threaded pin). The contact means mounting section of the second contact means may similarly comprise an external thread (threaded pin) or an internal thread (threaded recess).

In embodiments, the contact device may be configured as a socket contact device, a pin contact device, or a tab contact device. It goes without saying that other contact means may be used. The first contact means may be configured in part as a contact section of a contact device, in particular a socket contact. It goes without saying that the first contact section can also be configured in part as a pin contact, a tab contact or the like.

The power electrical mating contact means or the power electrical mating contact device are configured in a similar manner and/or in a complementary manner partly (e.g. pin contacts or tab contacts associated with socket contacts), wherein the terms contact means and mating means, contact means and mating means may be used analogously. This also applies to connectors and mating connectors (see below). Furthermore, the second contact means can be configured in part as a connection section of the contact device for a cable, in particular a crimp connection. It goes without saying that (compact) welded connections, soldered connections, glued connections, plug connections, threaded connections, etc. can also be used at least partially here.

The first contact means and/or the second contact means may be of unitary construction or one-piece in material. In the case of a one-piece construction in terms of material, the individual parts of the contact means (if any) are jointly fixed to one another, for example by welding, soldering, adhesive bonding, and preferably cannot be separated into individual parts without damaging the construction. The separate parts may be physically held together by way of active and/or inactive connections. In the case of a one-piece construction, there is only a single component part which can only be separated if it is destroyed. Thus, the integral contact means is manufactured from a single piece, which may be integral or monolithic for a part thereof.

In an embodiment, the first contact means and/or the second contact means may not be coated. In this case uncoated means that the actual material of the contact means in question is open to air and may not be provided partly under a coating containing e.g. nickel. The first contact means and/or the second contact means may be configured to be made of a copper alloy, in particular brass. Copper alloys of this type, for example CuZn37Pb2 or CuZn35Pb 2.

In an embodiment, the housing mounting section of the second contact means may be configured as a sealing seat for fluid sealing. Furthermore, the contact device may be configured as a subassembly, wherein the subassembly may have a contact device seal. In this case, the contact device seal may be mountable or mounted, for example, on the housing mounting section.

The exchangeable power electrical contact module according to the invention comprises an insertion housing with at least one contact segment socket, wherein the power electrical contacts of the power electrical contact arrangement can be arranged or arranged on/in the contact segment socket. In this case, the contact means can be received or received at least partially in an actively and/or non-actively locking manner, for example in/on the contact section socket. For example, the contact device may be latched or latched, may be clipped or clamped, and/or may be glued or glued, etc., e.g. onto/into the contact section socket.

In an embodiment, the insertion housing may comprise a base plate with a plurality of contact section sockets into which a plurality of contact devices are inserted. In this case, at least the base plate may constitute an insert housing of the contact module, wherein the insert housing is substantially in the shape of a tray (base plate, plate), or further in the shape of an (open) cage, a (open) tub or a boat. A plurality of protective sleeves may extend away from the base plate, with a contact segment socket provided in each protective sleeve. The contact means may be (partially) received in a contact section socket of the protection sleeve.

In embodiments, the base plate may be of integral construction or one-piece with the protective sleeve in terms of material. Furthermore, the insert housing may be of one-piece or unitary construction in terms of material. Similarly, it was seen above in terms of materials with respect to a one-piece or unitary construction. The insert housing may have a latching device or latching means for latching with the connector housing. The latching device may be configured, for example, as a latching spring, a latching arm, a latching lug, or the like. Furthermore, the latching means may be configured as, for example, latching elements, latching protrusions, latching lugs, latching shoulders, latching boundaries, latching edges, latching recesses, latching channel recesses, or the like. The latching module can have a first contact means or a contact device according to the invention.

The power electrical connector according to the invention or the power electrical mating connector according to the invention comprises a connector housing, wherein the connector housing has at least one contact section receptacle and the power electrical contacts of the device power electrical contacting means are arranged in the contact section receptacle. In this case, the contact device may be configured as a contact device according to the present invention. Furthermore, the connector or mating connector may have replaceable power electrical contact modules according to the invention. In this case, the connector or the mating connector may have a contact fixing device for fixing the contact device or the contact device of the contact module. In this case, the contact-securing means can be provided separately and/or in the connector housing.

The connector or mating connector may be configured as a plug, a coupling, a jack socket, or a flush connector. Furthermore, the connector or mating connector may be configured as a three-phase current connector, or a charging connector. The connector housing may have a latching device or latching means for latching with an insertion housing of the contact module (see above for the latching device or latching means). The associated latching means, or latching means associated with the latching means, and vice versa, may form an active and/or inactive combination in the mounted state. In this case, the combination is preferably configured to have a complementary shape and/or a complementary function in part.

The invention is described in detail below using exemplary embodiments and with reference to the attached detailed drawings, which are not to scale.

Detailed Description

The invention is explained in more detail below with reference to two embodiments of a power electrical contact device 10 (fig. 1 to 3 and 4 and 5), in particular for copper or aluminum cables, for the three-phase current field or the electric vehicle field, as well as an embodiment of a replaceable power electrical contact module 2 and an embodiment of a power electrical connector 1 (both shown in fig. 1). The information given about the connector 1 and the contact arrangement 10 can also be used for the mating connector 1 and the mating contact arrangement 10, respectively. That is, these names are similarly interpreted.

The invention is not limited to embodiments of this type, but naturally more basic results are obtained which can be used for other contact devices in the vehicle field or in the non-vehicle field, for example in the electromechanical field, in the energy-related field, etc. I.e. other variants can be derived therefrom without departing from the scope of protection of the present invention. In this case, the following statements relate to the axial direction Ax (axial), the longitudinal axis Ax or the rotational axis Ax, the radial direction Ra (radial) of the connector 1, of the contact device 10 and/or of the contact means 110, 120 of the contact device 10 in the circumferential direction Um (tangent), wherein two such ways are possible in each case.

The power-electrical (high-current/electric power) (mating) connector 1 according to the invention, which is configured in a linear manner in this case, is configured as a plug 1 (high-current plug 1, charging plug 1, shield plug 1, etc.) or as a coupling 1 (high-current coupling 1, charging coupling 1, shield coupling 1, etc.). It goes without saying that the connector 1 may be configured in an angled or curved manner. Furthermore, the connector 1 may be configured as a plug socket, an in-line connector, or the like. The power electronics (high current/electrical power) of the contact arrangement 10 according to the invention, which is configured in a linear manner in this case likewise, is configured as a crimp contact arrangement 10, wherein the contact arrangement 10 is further configured as a socket contact arrangement 10.

It goes without saying that the contact device 10 can be configured as a pin contact device, a tab contact device or the like. Furthermore, the contact arrangement 10 may be configured as a non-powered electrical contact arrangement 10, i.e. an electrical contact arrangement 10. Furthermore, the contact arrangement 10 may be configured as a (compact) welding contact arrangement, a soldering contact arrangement or the like (see below). It goes without saying that the contact device 10 can also be arranged in an angled or curved manner.

According to the invention, the contact device 10 is configured in a plurality of parts, in particular in two parts. That is, at least two sections or constituent parts of a single contact device 10 can be mechanically, electrically and/or electromechanically disconnected from one another and can be joined together again. In this case, the two sections or components can be produced separately from one another or formed from a single piece or integral part in terms of material (contact device 10).

The contact arrangement 10 preferably comprises two (power electrical, electrical)

contact devices

110, 120. In this case, the contact means 110 may be configured as socket contacts 110, pin contacts, tab contacts or the like, and in this case, the contact means 120 configured as connection means 120 may be configured as a crimp connection 120, a (compact) welded connection, a soldered connection, an adhesive connection, a plug connection, a threaded connection or the like. The contact means 110, 120 are held in one piece as a contact arrangement 10, but are held together in an easily releasable manner.

The two contact means 110, 120 of a single contact device 10, which can be separated from one another, form a contact region 15 or a connection 15 in the mounted state to one another (see fig. 1, 2 and 5), in which they can be separated from one another mechanically, electrically and/or electromechanically or can possibly be joined together again. The contact region 15 may be configured in part as an active and/or inactive connection 15. For example, (spring) plug connections (see fig. 1 to 3), screw connections (see fig. 4 and 5), latch connections, snap action connections (snap arrangement, etc.) etc. are used for this purpose.

Preferably, the contact section 110 of the contact arrangement 10 is configured as a first contact means 110 and the connection section 120 of the contact arrangement 10 is configured as a second contact means 120 of the contact arrangement 10. That is, the contact arrangement 10 has two

contact sections

110, 120 in the axial direction Ax, wherein the two

sections

110, 120 preferably form a complete axial section of the contact arrangement 10, with the exception of the common contact region 15 of the two

sections

110, 120.

For the mutual mounting of two contact means 110, 120 associated with each other, each contact means 110, 120 has a corresponding contact means mounting

section

111, 121, wherein the contact means mounting sections form the contact area 15 of a single contact device 10 between the contact means 110, 120 in the state in which they are mounted therein. The contact means mounting

sections

111, 121 are particularly configured such that they can be arranged or can be mounted on each other, possibly several times.

Preferably, in this case, the contact means mounting

sections

111, 121, which can be arranged on or mounted on one another, are configured partly in an active manner and/or partly in an inactive manner. The active and/or inactive connection of the mounting

sections

111, 121 may be configured as, for example, (spring) plug connections 111, 121 (see fig. 1 to 3), screw connections (see fig. 4 and 5), latch connections, snap action connections (snap arrangement, etc.), etc.

Thus, for example, the contact device mounting section 111/121 may be configured as a contact pin/contact spring ring 111/121 and the contact device mounting section 121/111 (corresponding to or partially complementary to it) may be configured as a contact spring ring/contact pin 121/111 (see fig. 1-3). Further, for example, the mounting section 111/121 may be configured as an internal thread (threaded recess)/external thread (threaded pin) 111/121 and the contact device mounting section 121/111 (corresponding to or partially complementary thereto) may be configured as an external thread (threaded pin)/internal thread (threaded recess) 121/111 (see fig. 4-5). It goes without saying that other electromechanical connections 15 for contacting the

device mounting sections

111, 121 can be used.

At least one contact means 110, 120 has a

housing mounting section

112, 122, which may be configured as a sealing seat (112, 122) for mounting the contact arrangement 10 on/in the housing 3, 20. If only one single housing mounting section 112/122 of the contact arrangement 10 is present on one of the contact means 110/120, the respective other contact means 120/110 is preferably held on/in the housing 3, 20 by means of the first contact means 110/120. Preferably, however, the contact means 110/120 of a single contact device 10 each have a housing mounting section 112/122.

Furthermore, one of the contact arrangement 10 or the contact means 110, 120 has a contact region 113 and one of the contact arrangement 10 or the contact means 120, 110 has a connection region 123. The contact region 113 may be configured, for example, as a socket region 113, a pin region, a tab region, and the like. The connector area 123 may be configured, for example, as a crimping area 123, a (compact) welding area, a soldering area, an adhesive area, a plugging area, a threaded area, etc.

Depending on the design of the

respective contact device

110, 120, the respective contact device mounting section 111/121, the respective housing mounting section 112/122, and/or the respective contact region 113 or connection region 123 may be formed offset with respect to one another in the radial direction Ra and possibly partially overlapping one another in the axial direction Ax, offset with respect to one another in the axial direction Ax and/or offset with respect to one another in the radial direction Ra in the contact device 110/120.

Thus, particularly in the case of a single contact device 110/120, the contact device mounting section 111/121 may be partially or substantially completely mounted in the housing mounting section 112/122 of the contact device 110/120 (see fig. 1-3). In this case, non-uniform radii of the contact mounting section 111/121 and the housing mounting section 112/122 may be achieved. Further, in the case of a single contact device 120/110, the contact device mounting section 121/111 may be disposed at an axial distance from the housing mounting section 122/112 of the contact device 110/120. In this case, the same or different radii of the contact mounting section 121/111 and the housing mounting section 122/112 may be achieved (see fig. 4 and 5).

Furthermore, the contact arrangement 10 or one of the contact means 110, 120 may have a contact arrangement seal 130. To this end, the

housing mounting sections

112, 122 are preferably configured as seal seats (112,) 122, against which the contact arrangement seals 130 are seated in a sealing manner. In this case, the contact device 10 with the contact device seal 130 may be configured as a subassembly 10.

One embodiment of a connector 1 is shown in fig. 1, wherein the connector 1 has a connector housing 3 or an outer housing 3 on/in which a replaceable power electrical contact module 2 or a replaceable high current contact module 2 or a replaceable electrical power contact module 2 is shown in its mounted position. The contact module 2 comprises an insert housing 20 or a contact module housing 20, which is configured in this case to be substantially formed in the shape of a boat. It goes without saying that a substantially disc-shaped (only the base plate 200, see for example below), substantially cage-shaped or substantially tub-shaped configuration can also be used.

The insert housing 20 includes at least one base plate 200, which may be configured as a tray 200, plate, or the like. The base plate 200 has at least one contact section socket 201 for holding a corresponding contact means 110/120 of the contact arrangement 10, in particular the first contact means 110. In this case, the contact means 110(, 120) are accommodated in the contact section receptacle 201 by means of their contact means mounting sections 111(, 121). The collar 114, which may be present on the axial ends of the mounting sections 111(, 121), prevents the contact means 110(, 120) from being inserted too far into the housing 20.

Preferably, at least one protective sleeve 210 or protective nipple 210 extends away from the base plate 200, in which protective sleeve or nipple the contact means 110 (120) or at least the actual contact region 113 of the contact means can be received such that an operator cannot make contact with the contact means 110 (120), which can be partially accommodated in the contact section socket 211 of the protective sleeve 210. The protection sleeve 210 is preferably configured in a substantially hollow cylindrical form.

The side walls 220, which may be provided at the radially outer wheels of the base plate 200, may make it easier to insert the contact module 2 into the connector housing 3. In this case, the sidewall 220 may extend substantially completely around the outer wheel of the base plate 200 in the circumferential direction Um. Similarly, the connector housing 3 may have a circumferential shroud 320 that may be substantially complete. The base plate 200 and the connector housing 3 or the side walls 220 and the shroud 320 have, in part, complementary latching means which are preferably releasable from each other, as a result of which the contact module 2 can be fixed on/in the connector housing 3.

According to the invention, the respective contact means 120, 110 of the contact arrangement 10, in particular the second contact means 120, can be held by the connector housing 3. For this purpose, the connector housing 3 has a contact section receptacle 301, in which the contact means 120(, 110) are received by means of their contact means mounting sections 121(, 111). The collar 124, which may be present at the axial ends of the mounting sections 121(, 111), defines a stop for the collar 114 of the other contact means 110(, 120) and an axial stop which may serve as a contact device seal 130.

The contact means 120(, 110) are preferably received in a rotationally fixed manner in the contact section receptacle 301 of the connector housing 3 or in the connector housing 3. Furthermore, the contact means 110(, 120) are likewise preferably received in a rotationally fixed manner in the contact segment socket 201 and the protection sleeve 210, or in the contact module 2. Preferably, the two contact means 110, 120, which may be separated by a spring slot, for example, are arranged in a substantially rotationally symmetrical manner in the socket region 113 or the contact region 113 configured as tab contacts.

The connector 1 according to the invention is designed such that the contact module 2 can be removed from the connector 1, or can be replaced by a second contact module 2, if, for example, the contact areas 113 of the contact means 110(, 120) are subjected to an excessive amount of wear. Therefore, the entire connector 1 need not be replaced, but only a part thereof.

The embodiment of the contact arrangement 10 shown in fig. 1 to 3 is described in more detail below, wherein fig. 1 and 2 show the contact arrangement 10 installed and fig. 3 shows the contact arrangement 10 uninstalled. In this case, the contact arrangement is arranged 10 times such that the two contact means 110, 120 of the contact arrangement can be inserted into or onto each other and can be disengaged from each other in a correspondingly linear manner, which is illustrated by the two broad arrows in fig. 2.

The first contact section 110 or the first contact means 110 of the contact device 10 comprises a contact region 113 configured as a socket region 113 on the free longitudinal end section. A housing mounting section 112, which in this case is not configured as a sealing seat, joins the contact region 113 axially further to the rear. A contact means mounting section 111, which is configured to contact the spring ring 111, for example in the form of a socket, then mounts the housing mounting section axially further to the rear. The collar 114 is preferably formed between the housing mounting section 112 and the contact means mounting section 111 in the first contact means 110.

The second contact means 120 or the second contact section 120 of the contact device 10 comprises on the free longitudinal end section a housing mounting section 122 which is configured in this case as a sealing seat. A collar 124 is preferably formed at the free end of the housing mounting section 122. The contact element mounting section 121, which is configured as a contact pin 121 or a contact bolt 121, is arranged in the housing mounting section 122, wherein the contact element mounting section 121 can be arranged partially or substantially completely in the housing mounting section 122, which housing mounting section 122 is hollow and spaced apart from the contact pin 121.

The connection region 123 of the second contact means 120, which is preferably configured as a crimping region 123, joins the housing mounting section 122 and the contact means mounting section 121 axially further to the rear. A securing area 125 for securing the contact means 125 is preferably provided between the connecting area and the housing mounting section, for which purpose corresponding latching means or latching means can engage or act on/in the securing area 125. In this case, the latching means or latching means may be a section of the connector housing 3, or an external component part, or may be formed on an external component part.

As shown in fig. 1 to 3, the second contact means 120 may be configured such that the contact pins 121 protrude out of the housing mounting section 122. In this case, when the contact arrangement 10 is in the mounted state, the free longitudinal end sections of the contact pins 121 can engage into the central recess 115 of the first contact means 110, wherein the central recess 115 is formed inside the housing mounting section 112 of the first contact means 110.

It goes without saying that the contact means mounting section 111 of the first contact means 110 may be arranged on the second contact means 120 and, similarly, the contact means mounting section 121 of the second contact means 120 may be arranged on the first contact means 110. Further, an arrangement of the external thread 121 (the threaded pin 121) and the internal thread 111 (the threaded recess 111) or an arrangement of the internal thread 111 (the threaded recess 111) and the external thread 121 (the threaded pin 121) may also be used instead of the arrangement of the contact spring ring 111 and the contact pin 121, similarly to the following embodiments.

The embodiment of the contact arrangement 10 shown in fig. 4 and 5 is described in more detail below, wherein fig. 4 shows the contact arrangement 10 uninstalled and fig. 5 shows the contact arrangement 10 installed. In this case, the contact arrangement 10 is configured such that the two contact means 110, 120 of the contact arrangement can be screwed to each other, which can be indicated by the two broad arrows in fig. 4. Accordingly, the two contact means 110, 120 can be disengaged from each other again by opposite rotational movements.

The first contact section 110 or the first contact means 110 of the contact device 10 comprises a contact region 113 configured as a socket region 113 on the free longitudinal end section. A housing mounting section 112, which in this case is not configured as a sealing seat, joins the contact region 113 axially further to the rear. The contact means mounting section 111 is configured as an internal thread 111 (threaded recess 111) and is provided in the housing mounting section 112, and preferably completely in the housing mounting section 112. The first contact means 110 preferably has no collar.

The second contact section 120 or the second contact means 120 of the contact device 10 comprises on the free longitudinal end section a contact means mounting section 121 which is configured as an external thread 121 (threaded pin 121) and protrudes from the second contact means 120. A housing mounting section 122 joins the contact means mounting section axially further to the rear, wherein a collar 124 is preferably formed between the contact means mounting section 121 and the housing mounting section 122. The housing mounting section 122 is in this case preferably configured as a sealing seat.

The connection region 123 of the second contact means 120, which is preferably configured as a crimping region 123, joins the housing mounting section 122 axially further to the rear. A securing area 125 for securing the contact means 125 is preferably provided between the connecting area and the housing mounting section, for which purpose corresponding latching means or latching means can engage or act on/in the securing area 125.
